I still have a strange problem. Sometimes when I load up a scene with a forest inside, some forest objects get loaded and some not. The "F" symbol is only shown. I have to select it plus go to "modify" tab. Then the point clouds show up.
Furthermore the Density is set from "Full" to "Dense". I definitely set it properly to "Full" because I did a render with it the day before.
Using Forst Pro 6.1.7 with Octane 2018.1 and 3dsmax 2019 latest SP.
